Theory of Information Entropy of Storage Capacity Curve of a River Basin

流域蓄水容量曲线的信息熵理论

The main results are as follows: ( 1) The changing pattern of storage root thickening rate expressed a double-peak curve, the first peak appeared at 50~ 70 DAP ( days after planting), and the second peak appeared at 120~ 165 DAP.

结果表明：（1）块根膨大速率变化动态呈一双峰曲线，第一个高峰出现在栽秧后50～70d，第二个高峰出现在栽秧后120～165d；

This paper presents a new precise evaluation method for time base and trigger characteristics of digital storage oscilloscope. By using sine wave curve-fit method, the time-base, the slope of trigger, trigger level, trigger delay, and the trigger jitter have been evaluated accurately.

本文提出了一种数字存储示波器时基和触发特性的精确评价方法，通过使用正弦波拟合法，其时基准确度、触发沿斜率、触发电平不确定度、触发延时误差以及触发沿晃动被精确评价；

Finally, the inability to make the storage curve of four parameters by the theory of unsteady flow is discussed and the conclusion that it is unnecessary to offer the storage curve of parameters to flood routing computation by the computer method of unsteady flow is reached.

文章最后还就用非恒定流理论制作四参数库容曲线的不可行性及用非恒定流电算方法为调洪演算提供多参数库容曲线的不必要性等问题进行了讨论。
